Sažetak
The basic equations of the quasiparticle-phonon nuclear model are derived for a finite rank nmax > 1 separable isoscalar and isovector multipole and spin-multipole particle-hole and particle-particle interactions between quasiparticles. It is shown that allowance for separable nmax > 1 interactions complicates the RPA calculations but almost does not lead to complications of calculations of the fragmentation of quasiparticle and collective states. It is stated that the QPNM can serve as a basis for calculating many characteristics of deformed nuclei. The QPNM with p-h and p-p interactions provides a good enough description of low-lying quadrupole, octupole and hexadecapole states in some deformed nuclei, which is exemplified by 168Er.
